Abstract
Nanocrystalline metal (Cu, Hg, Zn, Pi, Ph) sulfides with different shapes a nd different particle sizes have been successfully prepared in a formaldehy de solution of metal salt and thioacetamide by microwave irradiation. Powde r X-ray diffraction patterns indicated that the products were pure orthorho mbic Bi2S3 phase, cubic phase HgS, hexagonal phase CuS, cubic phase ZnS, cu bic phase PbS, respectively. The products were also characterized by transm ission electron microscopy. Ultraviolet reflection spectrum clearly indicat es the presence of quantum size effects in ZnS.
